Interesting video. Girls do know when you're interested in them, and will even lure you into it - even if they're not interested back. I've had this happen in the past. They set up all these "orbiters", and give them false hope - while acting oblivious to what they're doing. They're the ones who have ulterior motives - not just the guys. You'll find that women will set up a lot of things to their favor - only to play dumb, and act innocent. They're just as selfish as guys are - they just blame the guy, and make him look like the bad one. No matter what they do wrong - they'll act innocent, and claim everyone else is selfish and evil. Even if they cheat on someone, or play the whole world. Contrary to what you may believe, or they want you to believe - they DO know what they're doing. They just don't want other people to know that.
Manipulation aside, this is why you can't be chumped around by women. They have no interest in being your friend - after they reject you, and know you're interested in them. They're just feeding their egos, and playing you for a fool. The mixed messages come from the coniving nature in which this occurs. They want you to remain interested in them - and only them - and will go to great lengths to achieve this. They'll lie their asses off the entire time, and never admit to what they're doing. Even if they were interested in you at one point, and lost that - they still want you to remain interested in them. This never changes, and its why a lot of guys get confused - because, rather than admit to not being interested, or losing the interest they once had - they'll keep the false hope alive to keep the guys around, and still interested in them. They know that, if they tell them they're not interested, and just want to be friends, and don't flirt or tease - they won't get what they want from them. So, they lie and abuse their sexuality to keep the interest going. This is manipulation. They are using people, because they're selfish. All red flags.
If you show interest in someone, get rejected, and have that same person still want to be your "friend" - get out, and don't look back. You're just asking to get used. Don't fall for guilt trips or BS lines, either. You're not a jerk for not being friends with someone who's only using you and stringing you along. It will happen - if you allow it to. They know you're interested in them, and will feign interest in you - to keep you interested in them. They love knowing you want them, and can't have them. They'll play it to a tee. All while acting like they're interested in being your friend - with the potential for more to occur (only to be shot down with a lame excuse, or blown off with extreme rudeness every time). They'll also piss and moan, and call the guys selfish for refusing their one-sided friendship. Again, manipulation.
It doesn't matter when this occurs, either. A rejection means lack of interest. They're not trying to see how great and wonderful you are before getting involved with you, or any of that nonsense. They are using you. It's vital that you don't get lured into having interest in someone - only to be ****ed with afterwards. Some girls are very cruel and selfish. Either you're dating, or not. Don't get caught up in that grey area, because its usually no good. People typically aren't as genuine as we want them to be, or hope they are. A lot of them have ulterior motives, are selfish, will use others, and so forth. Keep your eyes open, and believe nothing they claim. Don't trust anyone until well down the line. If someone waltzes into your life, starts acting selfish, makes up excuses, tries to use guilt trips, etc - tell them to **** off. Don't get pushed around like this. Nobody is owed or entitled to anything.
They admit all this in the video, and its clear anyway. Women are not as stupid or innocent as they want you to believe. They are very intuitive and intelligent when it comes to things like this. They just play the victim to appear innocent and naive. The manipulative ones will also use it to their advantage. Notice how some of them walk away smiling in embarassment. They know they got caught, and aren't as clever as they think they are.
All that aside, these aren't quality women. They sound like college ****s. Quality, nice, decent, good-hearted women don't manipulate, use, or string people along. These are things you have to watch for, because not everyone is obvious in their awful behavior (ie, flamboyant jerks). You'll find a lot of people are like this. Seemingly decent and nice, but quite selfish and horrible. Pay attention to their actions and personalities; weed through the BS; find out what they're really like. Someone who's only interested in using you, and who lies to you about their intentions - isn't a good friend, and not worth keeping around. You'll find that these same people will likely disrespect you, and treat you as second-rate citizens. They will definitely also try to maintain their good person victim image going at all times. Don't fall for it, or any of their excuses.
Unfortunately, its things like this which require game to be necessary. It's like playing chess, really.
